GHG mitigation potential through sustainableland use change

Colombia and Peru contribute 0,46 and 0,3% to global GHG emissions

GHG Reduction commitment: 20% of BAU by 2030 (30%?)

> 50% Colombia and Peru GHG emissions are from AFOLU sectors

Introduction: context

Source: iNDCs (2015)

Objectives1. Characterize carbon emissions performance of identified systems (extensive,

silvopastoral, agroforestry)

2. Quantify emissions reduction of proposed sustainable changes within these

systems

3. Up-scale mitigation potential of sustainable LU changes• SAL project (1)• Secondary data (2)

CO2 sinks and sources

Systems characterization

Carbon pools

Land use change

Farming practices Firewood extraction, tree extraction for timber, use of fire, fertilizers (production, soils), livestock (enteric fermentation, feed, manure), transport

Crops

Pasture

Livestock

Fertilization, productivity, use of manure, etc.

Population numbers; feed supplementation; manure management

Secondary data, Emission

factors

Survey data Farming practices

Productivity, seeds, use of fire, cover crops, fertilizer, pesticides, herbicides, harvest, transportation, etc.

Results expression: functional unit (FU)

• Pros: useful for comparison across different

farming systems (that produce the same output)

• Cons: referring GHG emissions to certain products

must account for multi-functionality of livestock

• Pros: easier for comparison of systems that produce

different outputs

• Cons: doesn’t account for efficiency of production

(i.e. how it affects land use change elsewhere)

Products Farm (ha)

Land use change: survey

Agriculture practices: crops Inputs: fertilizers, herbicides, etc Soil management (e.g. till/no till) Transport Other: e.g. use of fire

Agriculture practices: livestock Population charact. Feed charact. Pasture

? Carbon pools Soil; woody biomass

? Integrate forest land use? Up-scaling

GHG accounting of local farming systems

What bigger picture can we learn from this project? How can we link it to

Colombia’s national goals -INDCs/NDCs? (Other mechanisms, e.g. REDD+)

Interested in integrating other land uses in GHG assessment, e.g. forest

Role of Silvopastoral and Agroforestry Systems in forest/landscape

connectivity

Summary of research interests within SAL

Collaborations with project members

• Soil and woody biomass carbon stocks -> Paul Peters (CIAT), Jaime Barrera

(SINCHI), others?

• Secondary data and possibilities for upscaling: Ricardo González, Jacobo

Arango (CIAT), Miguel Romero (CIAT), others projects? (e.g. LIVESTOCK+?)

• Terra-i team? (e.g. GHG of deforestation, forest fragmentation)

• Others?
